The Linking pin model is an idea developed by Rensis Likert in which an organisation is represented as a number of overlapping work units in which members of one unit are leaders of another. In this scheme, the supervisor/manager has the dual task of maintaining unity and creating a sense of belonging within the group he or she supervises and of representing that group in meetings with superior and parallel management staff. These individuals are the linking pins within the organisation and so they become the focus of leadership development activities.
